Lightning conducter, while setting up lightning conducter in the strong location of lightening activity, or installs circuit metal oxide arrester；Its center line
Steel tower lightning protection in road it is particularly important with it is crucial.
In general grounding-for-lightning device, wire is used, one end connects the pedestal of high-pressure tower, and soil is goed deep into one end
In, buried lightning protection device is connected, because wire is excessively soft, easily occurs the damaged and accident such as come off, influences lightning protection
The work operation of device；Replace being attached by the way of wire using a kind of bonding jumper later, but bonding jumper is straight in itself
The list structure of line, the pedestal of high-pressure tower is typically provided with step, and bonding jumper can not enter walking after installing according to the shape of step
Line, therefore space-consuming, than larger and exposed around pedestal, potential safety hazard is than larger.
Therefore such case is directed to, it is necessary to design a kind of processing unit (plant) of bonding jumper, can be according to difference by bonding jumper
The shape of pedestal and step carries out any bending process so that bonding jumper can be close to pedestal and step cabling.
The content of the invention
Technical problem to be solved in the utility model is to overcome the defect of prior art there is provided one kind is simple in construction, system
Facilitate, straight line bonding jumper can be carried out the bending of any angle and length, bonding jumper is processed into by easy to disassemble and maintenance
High-pressure tower pedestal can be close to and ledge surface walks wire shaped, so as to improve the security of high-pressure tower lightning protection device, strengthen lightning protection
The transmission tower down conductor bending device of device intensity.
To achieve these goals, the utility model uses following technical scheme：
Transmission tower down conductor bending device, it is characterised in that include and be provided with one on a base, base
The processing unit (plant) that metallic plate is surrounded, processing unit (plant) include before and after two blocks of side plates and top top plate, surround solid rectangle；Institute
Charging aperture is hollowed out on the two blocks of side plates stated to pass through for bonding jumper, two charging aperture shapes and sizes are identical, and position pair
Claim, charging aperture is shaped as rectangle, its upper end reaches ceiling edge, lower end keeps 20-30mm distances with base；Described top plate
Centre, through there is vertical screw rod, is thread matching structure, rotatable rising or decline, spiral between screw rod and top plate
Handle is installed, bottom is connected with the briquetting that a section is isosceles triangle, and briquetting is list structure, and its summit is erected at the top of bar
Directly down, a line ball is formed.
In such scheme, the side plate of described processing unit (plant) be divided into above and below two parts, the latter half is fixedly welded on bottom
On seat, it is provided between top half and the latter half and is provided with fastening bolt on coincidence part, coincidence part and is fixed, conveniently torn open
Two parts above and below unloading.
In such scheme, the cross sectional shape of described briquetting can be preferably isosceles right triangle, its right-angled apices
For fillet, prevent from breaking bonding jumper and produce impression.
In such scheme, a ball bearing, ball bearing are additionally provided between described screw rod bottom and briquetting
Outer ring be fixedly connected with briquetting, inner ring socket screw rod.
In such scheme, the lower surface of described top plate is additionally provided with a reinforcement sleeve and passed through for screw rod, and
Strengthen being also equipped with screw thread and screw rod cooperation in sleeve.
The utility model is by adopting the above-described technical solution, have the advantages that：
